Notes

1From isotope relations.
2Spin doubling constant γ0 = +0.076. All lines are diffuse owing to predissociation.
3Breaking-off in emission at low pressure above N'=19 and 4 in v'=0 and 1, respectively Khan, 1963, 2. Perturbations.
4Strong perturbations.
5Franck-Condon factors Singh and Srivastava, 1968.
6Perturbations.
7Spin doubling constant γ0 = -3.81 N < 10 Watson, Fredrickson, et al., 1936. For a more elaborate evaluation of the spin splitting including higher-order correction terms see Veseth, 1971.
8A0 ~ +300. See also 9.
9Very large Λ-type doubling, see Watson and Fredrickson, 1932, Veseth, 1971, 2. The constants given here are effective values; see, however, Veseth, 1971, 3 who has evaluated the true constants by taking into account several usually neglected corrections to the rotational energy formulae for a 2Π state.
10From Watson, Fredrickson, et al., 1936; spin doubling constant γ0 = 0.122 Watson, Fredrickson, et al., 1936. Edvinsson, Kopp, et al., 1963 give B0 = 3.6336, D0 = 13.39E-5.
